Hi Phil

I like the bent copper wire to see which piston is moving......

I had removed all the plugs to facilitate turning the engine and some fluid/lube did spill out when the engine partly turned over.

Before turning the engine over, I loosened up all the valves with light taps from a hammer.... then Grant manually depressed each valve with long screwdriver..... all valves moved and sprang back.....

I am afraid that nothing short of removing the head will give me a clear answer but will try the wire trick first.

Stay tuned.

Bob
